Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the defect that the currently applied Monochamus alternatus attractant formula is unscientific and has a poor trapping effect, and at the same time, the release material cannot reach the optimal release amount, which limits the trapping effect, and provides a monochamus alternatus attractant.

Embodiment 1

[0016] The trapping experiment was carried out in Xindeng Town and Dongqiao Town, Fuyang City, Zhejiang Province. We mix plant-derived pheromones (a-pinene, turpentine, ethanol, guaiacol, etc.) in a certain proportion, put them in a slow-release bottle (low-density polyethylene), and then mix the pheromones of Monochamus alternata (2-undecyloxy-1-ethanol) in a slow-release bag (low-density polyethylene). Set 5 traps for each recipe, randomly distributed, and every two traps are separated by 30-40m. Beginning in early May in 2015 and 2016, and continuing until the end of August, the trapping results are checked every week. This period of time happened to be the main period of adult beetle activity, and the number of long beetles trapped by each trap was recorded. The following test methods are the same as above.

[0023]

[0024]

[0025] The results of Example 2 show that firstly, formula 2 and formula 3 respectively added terpenes such as β-pinene and camphene on the basis of α-pinene in formula 1, but the result inhibited the growth of Monochamus alternatus on the contrary. Therefore, α-pinene is the best terpene substance, and other pinene substances should not be added.

[0026] Second, formulas 5, 6, 7 and 8 added a certain amount of guaiacol and 4-methylguaiacol on the basis of formulas 1 and 2, respectively. The trapping results showed that adding guaiacol and 4-methylguaiacol -Methyl guaiacol was significantly improved compared with the original formula, and the improvement rate reached 9.3%-18.8%. Among them, formula 6 improved by 15.8% on the basis of the original formula 4, and showed the highest trapping effect. Guaiacol and 4-methylguaiacol are volatil...

Embodiment 3

[0029] Table 3 Tests of different doses of terpenes and fermented substances (Zhejiang Fuyang Dongqiao, 2015, 5.10-6.14, N=5)

[0030]

[0031] The results of Example 3 show that the different doses of terpenes and fermented substances have a very significant impact on the trapping results, and when the ratio of formula 3, turpentine and ethanol is 3:1, the trapping effect is the highest, and the ratio is 1 Worst during: 1, but the trapping effect of the formula 1-5 that adds ethanol is all significantly higher than 2.5 times of the formula 6 that does not add ethanol, difference is very significant, so ethanol is a kind of important synergistic substance, and turpentine and ethanol The best ratio should be 3:1.

Abstract

The invention discloses a Monochamus alternatus attractant which comprises a plant-derived pheromone and an aggregation pheromone. The plant-derived pheromone comprises the following components in parts by volume: 60-75 parts of turpentine or alpha-pinene, 18-30 parts of ethanol, 0-5 parts of guaiacol and 0-5 parts of 4-methyl guaiacol. The aggregation pheromone is 10-100 mu L / lure 2-undecyloxy-1-ethanol. The application method comprises the following steps: the plant-derived pheromone is released by a slow-release bottle, wherein radial bulge lines are arranged in the cap of the slow-release bottle, the slow-release bottle is prepared from low-density polyethylene (LDPE) with the density of 0.910-0.925 g / cm<3>, and the wall thickness of the slow-release bottle is 0.20-0.70mm; the aggregation pheromone is released by a slow-release bag, wherein the slow-release bag is prepared from LDPE with the density of 0.910-0.925 g / cm<3>, and the wall thickness of the slow-release bag is 0.04-0.15mm. The average trap quantity per week of each Monochamus alternatus attractant is up to 59.01; the drug effect can stably stay for 2 months or so; and thus, the Monochamus alternatus attractant can greatly lower the population density of Monochamus alternatus and inhibit the pine wood nematode disease from propagation and transmission.

Description

technical field [0001] The invention relates to the field of monochamus alternatus control, in particular to a monochamus alternatus attractant and a method for using the same. Background technique [0002] Pine xylophilus disease is called "cancer" of pine trees. Its pathogen, Pine xylophilus, is the largest foreign invasive species in forestry in my country, and Monochamus alternata is its main vector in China. Since the first discovery of pine wood nematode in Nanjing Sun Yat-sen Mausoleum in 1982, it has caused serious harm in most provinces south of the Yangtze River Basin in my country, posing a huge threat to my country's forest ecological health system, and has become the top priority of the local forestry department. Preventing and controlling the pine wood beetle and cutting off the transmission medium of pine wood nematode disease have become the key to the prevention and control of pine wood nematode disease. At present, the control of pine wood nematode disease...
